Sixseventeen is a world built on music, fashion, freedom and escape—a temporary departure from the city where Villa Simonne becomes ours until morning.

On 25 October 2026, Nouveau Society takes over an entire castle in Houghton, Johannesburg, transforming it into a Halloween world filled with music, mystery, connection and unforgettable memories.

Inspired by celebrity mansion parties, The Great Gatsby and the theatrical spirit of Halloween, Sixseventeen brings elegance and fantasy together within Villa Simonne’s grand rooms, outdoor spaces and timeless architecture.

This is more than an event.

It is an environment you step into—a chance to leave the outside world behind, become whoever you choose and experience the night without limitations.

As the afternoon fades, the music rises and the estate transforms.

Halloween fashion takes centre stage, turning Villa Simonne into a living display of creativity, character and personal expression. Guests are encouraged to arrive in their best Halloween outfits. Those who choose not to dress for Halloween must wear a football shirt.
